Fumes for all

From
Andrew Roberts

So Ford has recognised that air pollution levels are higher in cars than at
the roadside. But rather than reduce the amount of poisonous gas that their
vehicles emit, they are just proposing to spread it out more evenly with their
patent(5 August, p 7).

I’m surprised that they’re stopping at that. Surely their boffins could use
the airflow around the vehicle to blow the fumes to the side of the road, to
make sure that pedestrians and cyclists get their fair share too.
